wire from sending unit may be grounded/shorted out
Faulty sending unit.
Had the same problem - turned out we bent one of the prongs on the oil pressure switch when we were connecting it.
Fuel pressure (ignition key turned to on, engine not running): 50 to 60 psi
My 2002 Saturn was out of oil, oil was replaced but when I cranked it and drove it black smoke came out of the muffler and a fan keeps running after the car is turned offf. Do I have a major proplem
day time running module on drivers fender back by the brake booster needs to be replaced
The blower resistor is internally shorted to power and needs to be replaced.
The valve is not be diverting all the water. This valve may need to be replaced.
May be build up in the valve itself or the shower head.
It turned out to be the alternator going bad. Replaced alternator. No more growling.
Usually it is NOT a problem with the sending unit. Low oil pressure is typically caused by worn rod and/or main bearings. This is typically caused by poor engine maintenance. THIS IN FACT TURNED OUT TO BE A BAD OIL SENDING UNIT. BY THE WAY THE THIS ENGINE IS MAINTAINED PROPERLY. Check for loose grounds to engine. There are several. My 2001 Aurora has had sevral oil pressure transducers replaced. Just recently right after another was replaced the car was on the rack at the AC mechanics shop. He noticed an arcing ground to the engine. It is possible that the electricl surging has been burning out the semiconductor in the transducer. The same mechanic found a broken ground to the compressor clutch and a leaking AC sensor. Fixed them all and the AC works! Hope he also fixed the oil pressure sender problem.
I have a 95 pathfinder and had the same problem with fuel pump fuses blowing. It turned out to be that the fuel sending unit had to be replaced. . Try cleaning the six contacts on top of the sender unit make sure they are isolated
Try getting the PCV pipe replaced. Mine had a problem with it conking-out at stops and on turns and that turned-out to be the problem. It could also be a vacuum leak.
